Metal Ion Toxins and Brain Aquaporin-4 Expression: An Overview
Metal ions such as iron, zinc, and manganese are essential to metabolic functions, protein synthesis, neurotransmission, and antioxidant neuroprotective mechanisms. Conversely, non-essential metals such as mercury and lead are sources of human intoxication due to occupational activities or environmental contamination. Essential or non-essential metal accumulation in the central nervous system (...
متن کاملPhysiological roles of aquaporin-4 in brain.
Aquaporin-4 (AQP4) is one of the most abundant molecules in the brain and is particularly prevalent in astrocytic membranes at the blood-brain and brain-liquor interfaces. While AQP4 has been implicated in a number of pathophysiological processes, its role in brain physiology has remained elusive. Only recently has evidence accumulated to suggest that AQP4 is involved in such diverse functions ...
متن کاملRole of melatonin receptors in the effect of estrogen on brain edema, intracranial pressure and expression of aquaporin 4 after traumatic brain injury
Objective(s): Traumatic brain injury (TBI) is one of the most common causes of death and disability in modern societies. The role of steroids and melatonin is recognized as a neuroprotective factor in traumatic injuries. This study examined the role of melatonin receptors in the neuroprotective effects of estrogen. Materials and Methods: Seventy female ovariectomized Wistar rats were divided in...
متن کاملMolecular Dynamics Simulation of Water Transportation through Aquaporin-4 in Rat Brain Cells
This paper investigates the mechanism of water transportation through aquaporin-4(AQP4) of ratbrain cells by means of molecular dynamics simulation with CHARMM software. The AQP4 wasembedded into a bilayer made of Dimystroilphosphatylcholine (DMPC). The results illustrate thatwater molecules move through AQP4's channel with change of orientation of oxygen of eachwater molecule.
متن کاملexpression of glucose transporter 4 (glut4) is increased by cinnamaldehyde in c2c12 mouse muscle cells
background: in diabetes mellitus because of the absence or insufficient sensitivity to insulin, glucose transporter protein in cell membrane, glucose transporter 4, is decreased. glut4 is the major glucose transporter in skeletal muscle and adipose tissue, which is under control of insulin. it remains, however, unclear whether cinnamaldehyde plays a regulatory role(s) or not. objectives: the ob...
